Very nice Brett. I wonder if the delicate blue reflection nebula is in your data. With 10 hours it most likely is. It looks like some minimum filter distortions in the star fields in the bottom left of the image. Did you use some minimum filter?
Lots of stuff happening here Brett. I kept looking for a wolf in the bright stuff until I twigged that the wolf (veryrealistic) was a dark nebula, howling at the moon(?). Nicely done.
